Even I denied snow_fall, it still fall and cover the ground.

Hi, thanks for the issue.

Well it seems like the mod is using some custom logic to check if it should place snow and does not use the vanilla check in addition.

It might be possible to cover this. I need to take a deeper look at it. Maybe they need to adjust their code to adhere more to the vanilla way.

If I have time, I'll give it a shot and maybe even suggest a change in a PR.

Best regards
